Everything about Thigh totally explained
In
humans the
thigh is the area between the
pelvis and
buttocks and the
knee. Anatomically, it's part of the
lower limb.
The single
bone in the thigh is called the
femur. This bone is very thick and strong (due to the high proportion of
cortical bone), and forms a
ball and socket joint at the
hip, and a condylar joint at the knee.
Fascial compartments
In cross-section, the thigh is divided up into three
fascial compartments. These compartments use the femur as an axis, and are separated by tough
connective tissue membranes (or
septa). Each of these compartments has its own
blood and
nerve supply, and contains a different group of
muscles.
Blood vessels
The arterial supply is by the
femoral artery and the obturator system. The lymphatic drainage closely follows the arterial supply.
The deep venous system of the thigh consists of the
femoral vein, the proximal part of the
popliteal vein, and various smaller vessels; these are the site of proximal
deep venous thrombosis. The
venae perfortantes connect the deep and the superficial system, which consists of the
saphenous veins (the site of
varicose veins).
Thigh weakness
Thigh weakness can result in a positive
Gowers' sign on physical examination.
